Akerly-Childs AC-RC4165 Tapered Piston Ring Compressor for 4.165-Inch Bore

The Akerly-Childs AC-RC4165 piston ring compressor is designed for installing pistons into engine cylinders with a 4.165-inch bore. Its tapered profile helps guide piston rings smoothly into the cylinder, supporting efficient assembly and helping reduce the risk of ring snagging or improper alignment during installation. This tool is well suited for engine builders, professional technicians, and performance automotive applications.
Constructed from lightweight aluminum, the Akerly-Childs AC-RC4165 is easy to handle while providing the rigidity needed for consistent piston installation. The black anodized finish adds surface protection and gives the compressor a durable, professional appearance. Its dedicated bore size provides a focused fit for compatible engine applications rather than relying on a one-size-fits-all design.
The Akerly-Childs AC-RC4165 tapered ring compressor is supplied individually and is intended for use with pistons and cylinders matching its 4.165-inch bore specification. Before installation, verify the bore size and ensure the piston rings are properly positioned according to the engine manufacturer's recommendations. This compressor is not air powered and is suitable for standard manual engine assembly work.
